Ok, The PVC status would never go down till the switch reports it as down, and only then will the line protocol go down.
I have come across this scenario a couple of times (with ATM, concept is the same). And the trick is to use a routing protocol between the 2 routers, a routing protocol senses that the keepalives / hellos are not being answered and so will consider the neighbor as down, and in turn will activate the isdn circuit. You could also use dialer watch, watch a route and if that route goes down (when one end of the frame goes down) activate the isdn. hth Nick Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=35649&t=35389 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
